Prevention and Intervention Tools for Depression


Symptoms of Depression in Adolescents

During the preteen and teen years, it can sometimes be difficult to know whether your child is dealing with a mental or behavioral health challenge such as depression, substance use or bullying, or if the changes in behavior you’re seeing are simply a matter of your child going through a natural transition.  However, it’s important to begin a conversation to find out what is going on in order to know how to best help your child. It’s especially important to take note if several symptoms are occurring in combination, or are occurring over a prolonged period of time.  Even if they’re not dealing with a serious issue, taking the time to talk with them can still be incredibly beneficial.

Sources of Depression in Adolescents

The cause of depression in adolescents can vary from one individual to another.  There is no one single universal source of depression.  However, some of the following factors can play a role.

Childhood Trauma

Traumatic events in childhood can impact an individual’s brain in a way that makes them more likely to deal with depression.  These events can include abuse, physical violence, sexual assault, severe accidents, war, natural disasters, death of a loved one, and witnessing violence.  If an adolescent has experienced early childhood trauma, it’s important that the treatment they receive for depression is trauma informed.


Depression is more common in individuals with blood relatives who deal with depression.  If their parent or grandparent has gone through depression, a child can be at greater risk.

Brain Chemistry

Neurotransmitters such as dopamine and serotonin play a major role in regulating mood.  When neurotransmitters are imbalanced or deficient, depression can result.


During the preteen and teen years especially, hormonal changes can affect mood and contribute to depression.

Learned Helplessness

Adolescent depression can be caused or aggravated by habits of negative or unhealthy thinking.  When faced with challenges or difficulties, some youth will work to find a solution, whereas others will remain stuck in the problem, which can lead to depression.
